2) Enter Developer options (in settings) 
3) Turn on "Enable APZ for all content."
4) Open the Marketplace. 
5) Begin to scroll downwards and upwards.

This seems pretty obvious that this a bug with `position: fixed`. We're not doing anything special that any other site is doing (using flexbox is certainly an option but obviously sites using `position: fixed` should not break in Gaia).

This seems related to bug 950993.
